Video settings
You should check and adjust the video settings so that they are appropriate for the production. These
settings include the video source, format, and output.
From the main menu, select
Video
and configure as follows.
Table 12: Video settings
Setting
Description
Video Source
Specifies the video source (RF or ASI).
‘RF’ is the default setting and means that the source for video decoding is
taken from the diversification of the rear panel RF inputs (RF1
–RF8) on
the receiver.
‘ASI’ means that the source for video decoding is taken from the rear
panel ASI IN.
Video Format
Specifies the video mode and frame rate. This is defined by the
production format.
If the video format is incorrect, you will either get no video image or a
corrupted image.
Frame Sync
Sets the Lines and Pixels offsets to synchronize the image to the
production workflow.
You can synchronize the image by connecting a B&B or tri-level signal to
the
receiver’s SYNC connector. If the parameters are incorrect, the video
may not be synchronized at the video mixer, which will give production
issues when cutting between different images.
If you are required to frame sync your image, then it does not matter what
values are applied here.
Video Latency
Sets the required sync offset to delay the video feed. The required offset
depends on the transmitter, so you must check and select the type of BSI
transmitter that you are using. If set incorrectly, the image may freeze or
result in picture judder.
If you are using third-party equipment, consult BSI Technical Support who
will advise on the correct setting.
Note that ‘BSI Freedom Tx (Low Delay 1080i)’ only needs to be applied
when a Real Freedom Camera Back Transmitter is used in ‘Low Delay’
and ‘1080i’ format. For all other cases, set the video latency to ‘BSI
Freedom Tx’ when a Real Freedom Camera Back Transmitter is used.
This includes ‘Super-Low Delay’ mode.
Video Output
Sets the video output from the rear panel SDI 1 and SDI 2 connectors.
‘Level A’ is the default, and almost all production workflows will handle
either. Some obscure production workflows may only be able to handle
‘Level B’.
‘Level A’ directly
maps an uncompressed 1080p/50 video stream into a
serial digital interface operating at a nominal rate of 3 Gbit/s.
‘Level B’
multiplexes the two signals from the dual-link format
of a
1080p/50 video stream into a serial digital interface operating at a nominal
rate of 3 Gbit/s.
